宏修改，改变 ModernCV

Question

您给出的代码中存在一些误解和错误。但让我们一步一步地看一下。

问题一：\par\addvspace{#1},起什么作用？ 新的宏\cventry定义如下\renewcommand*{\cventry}[7][.25em]，也就是说，它有一可选参数（第一个参数#1，取预定义的值.25em）和六非可选参数#2- #7。命令\par开始一个新段落，\addvspace{#1}然后命令添加长度为的垂直空间#1，通常是（预定义）.25em。这确保所有文本彼此之间的距离相同。
因此，您必须使用\cventry[0pt]...您习惯的命令\cventry[]...来摆脱多余的空间。

问题b：如何调整宏中文本换行的边界（即限制为列）？正如您已经在谈论列一样——您确实需要——使用表格来完成\cventry或\cvpdentry。这意味着，您可以在\ifx&#7&或内添加第二个表格\ifx&#4&，以使第一列不重叠。相反，您l在表格中使用的列使用p{15cm}列：\begin{tabular*}{\textwidth}{p{15cm}@{\extracolsep{\fill}}r}%。对于命令，\cvpdentry我们得到以下代码：

%\cvpdentry[addvspace]{institution/employer}{localization}{optional: comment/job description}
\newcommand*{\cvpdentry}[4][.25em]{
  \begin{tabular*}{\textwidth}{p{15cm}@{\extracolsep{\fill}}r} % <======
      {\bfseries #2} & {\bfseries #3} \\ %
  \end{tabular*}\par% <=================================================
  \ifx&#4&%
    \else{%
      \begin{tabular*}{\textwidth}{p{15cm}@{\extracolsep{\fill}}r}% <========= 
        {\small#4} & \\
      \end{tabular*}%
    }%
  \fi%
  \par\addvspace{#1}%
}

您是否注意到，我删除了您的第 8 个参数，现在不再需要它了……

问题c：如何扩展与 \section 和 \subsection 相关的行以覆盖整个页面的宽度（它们无法到达文档/文本的右边缘）？我担心这是个误解……这里真正的问题是您正在使用\item插入项目符号。但现在\textwidth您的表格的正确计算失败了。您必须像这样重新计算正确的表格宽度：（\textwidth-\labelwidth-\labelsep这里的“标签”是使用的项目符号）。在下面的 MWE 中，我在 commad 中显示了正确的计算\cventry，如您在生成的 pdf 屏幕截图中看到的那样。
margins包裹选项geometry错误，必须是margin……
